Embodiment 1

[0031] figure 1 Is an embodiment of the present invention in a flowchart of a method of determining the motion information, for example, using medical imaging device applicable to embodiments of the present invention to treat the sample prior to detection, the scanning table of vibration information included in medical imaging device for detecting Condition. The method of performing motion information determination means, the apparatus implemented by software and / or hardware, and in particular to medical imaging equipment disposed. Wherein the medical imaging device may be a computer tomography (ComputedTomography, CT) equipment.

[0032] like figure 1 Method for determining the one shown in vibration information, comprising:

[0033] S110, obtaining the scan data produced by scanning the phantom.

[0034] Wherein, the mold may be a uniform material provided with a certain hardness of the object, for example, a metal material or a hard plastic molded body. Illustratively, metal...

Embodiment 2

[0052] figure 2 Example II is an embodiment of the present invention, a flowchart of a method of determining motion information, embodiments of the present invention is optimized to improve the technical solution based on the above embodiment on.

[0053] Further, the operation of "phantom acquired scan data generated by scanning" refined as "scan data acquired in the scan of the scanning table phantom generated at different times"; corresponding to the operation "according to the scan data, to determine the actual mold body centroid coordinates sampled at different angles "refined as" scan data according to the acquired each time, respectively, to determine the actual coordinates of the centroid time of the mold body at different angles sampling "; Accordingly, the operation of "the actual centroid of each of the coordinates, the scanned information determining the motion of the carrier bed phantom" refined according to the actual coordinates of the centroid, respectively OK "ea...

Embodiment 3

[0071] Figure 3A Is a flowchart of a method of determining information of a medium according to a third embodiment of the present invention, vibration, embodiments provide a preferred embodiment of the present invention.

[0072] like Figure 3A Method for determining the one shown in the vibration information, is applied to CT apparatus, comprising:

[0073] S301,, placed on a scan bed of metal needle axis scan, scan data obtained.

[0074] Wherein the diameter of the metal needle is about 3mm, a length of about 50mm, a generally cylindrical metal pin. Approximate metal needle scanning aperture CT apparatus along the rotational axis disposed. As close to the edge of the scanning aperture when a metal needle, when the subsequent fitting of the results more accurate curve fit, so in order to ensure accuracy, preferably a metal needle is placed close to the edge of the scanning aperture.

[0075] S302, pre-scan data, to reduce background noise.

[0076] Wherein the pretreatment incl...

Abstract

The embodiment of the invention discloses a vibration information determination method, device, medical imaging equipment and storage medium. The method includes: acquiring scanning data generated by scanning the phantom; determining the actual centroid coordinates of the phantom at different sampling angles according to the scanning data; Scan table vibration information. The technical solution of the embodiment of the present invention determines the vibration information of the scanning bed in the medical imaging equipment based on the scanning data generated by the medical imaging equipment scanning the phantom, without additionally introducing other hardware equipment for auxiliary detection of the vibration information, reducing manpower and material resources At the same time, because there is no need for the introduction of hardware equipment and the migration of software methods corresponding to vibration information, the sources of errors and error transmission are reduced, thereby improving the measurement accuracy of vibration information.

Description

Technical field [0001] Embodiments of the present invention relates to medical imaging technology, and more particularly, to a method for determining vibration information, apparatus, medical imaging device and a storage medium. Background technique [0002] When using medical imaging device for scanning an object to be detected, the scanning table and the greater impact the stability of the object to be detected is present in the image quality of the image forming apparatus. When the scanning table and the object to be detected the presence of vibration during the scanning process, the scan data generated by scanning there will be discontinuity, and further based on the reconstructed image scan data will produce a high density or low density artifacts. So shake detected scanning bed is critical in the image during the scanning process. [0003] The prior art when the detected vibration of the scanning table, usually with additional medical imaging device for video cameras, hardw...
